Abstract

Background: Anastomotic leak is one of the most dreaded complications after intestinal anastomosis. The prevalence of anastomotic leak is 0.5%-30% in literature and resulting mortality rate is 10%-15%. Various risk factors are known to be associated with it. This study was undertaken with the aim to identify and evaluate these predisposing factors.

Methods: A prospective study was conducted from March 2019 to February 2020 at Teerthankar Mahaveer medical college and research centre, Moradabad. All patients undergoing hand-sewn gastro-intestinal anastomosis electively as well as in emergency were included in this study. The total number of cases studied were 80.

Results: Post-operative anastomotic leaks were present in 10% and associated mortality was 100%. Increasing age was associated with leakage (p=0.02) and 75% patients with leaks were male. The following were observed to be significant risk factors associated with anastomotic dehiscence: diabetes mellitus (p=0.05), pallor (p=0.01), low haemoglobin (p=0.003), altered TLC count (p=0.008) low serum protein (p=0.001), albumin (p=0.001) longer operative time (p=0.02). Other predisposing factors like serum creatinine, hyperbilirubinema, elective/emergency surgeries, contamination of peritoneal cavity and time taken to perform the anastomosis were insignificant statistically.

Conclusions: This study identified and assessed the various risk factors associated with anastomotic leaks and found age, sex, anaemia, sepsis, hypoproteinemia, hypoalbuminemia, increased operative-time to be significant and we concluded that controlling these factors will help in minimizing the chances of anastomotic dehiscence.
